Starch and water will be the best negative control
Explanation:
Negative control sample is a sample that will not give change in an experiment.
Starch and water will be the best negative control. This is because, starch is broken down by HCl to monosaccharides in the Benedict test which is the test for reducing sugar
Distilled water remain a negative control because it remain blue which means it does not reduce sugar with starch solution.
Water plus us a negative control for Buiret test (protein) and Benedict(reducing sugar) because it does not indicate the presence of protein and reducing sugar.

And these studies do show that on average, identical twins are more similar than fraternal twins.
